Product:Poly naphthalene sulfonate sodium salt (PNS)
Benefits:
-Improves the flow properties of the concrete mix by dispersing the particles and
breaking up agglomeration by electrostatic repulsion.
-Improves the rheological and mechanical properties of concrete such as
workability, compressive and flexural strengths, modulus of elasticity.

-Good durability and sustainability
Usage:
Redwall PNS is a major ingredient in different types of Superplasticizer
formulations
Dosage:
-Normal dosage rate: 200-1000g per 100kg of cement
-Other dosages may be required depending on specific conditions
-Redwall PNS fluidified concrete remains workable for approximately 90 minutes
at 20oC
-Duration of workability also depends on:
-type of cement-nature of aggregates
-method of mixing-method of transportation
-ambient temperature
-When added at normal dosages, it will not significantly affect the concrete’s
hydration heat
Packaging, Storage
-supplied in 1000kg and 1250kg bages
and Handling:
-storage at room temperature is recommended
Safety and Handling
-Mildly alkaline material
precautions:
-Eyes: direct contact may cause irritation
-Skin: prolonged contact may cause irritation
-Ingestion: May be harmful
-DON’T TAKE INTERNALLY
-Wash thoroughly after handling
